Describe the role of the kidney in
correcting acid-base imbalances. What two systems are involved in acid-base balance? Bicarbonate Buffer System
Component CO2 + H2O Renal
Component H2CO3 H+ + HCO3- + Na+ Cl- or HCO3- K+ or H+ To Correct an Alkalosis
• Respiratory system
– decreases respiratory rate, retaining CO2.
The carbonic acid produced dissociates
into H+ (which helps neutralize excess OH-)
and excess (unneeded) bicarbonate ion. • Kidney
– Helps eliminate excess bicarbonate ion by
reabsorbing less bicarbonate and more
– Helps retain needed H+ by secreting less
H+ and more K+. To Correct an Ac...
